Carlo Rovelli on the Physics and Philosophy of Time

HN commenters point to it as a lucid, general-audience lecture that shows how wrong common conceptions of time are, often in threads on entropy and the arrow of time.

Physicist Carlo Rovelli gives a public lecture at the Royal Institution on how our understanding of time has changed, from Boltzmann and Einstein to quantum theory and loop quantum gravity. He blends physics, philosophy and art to argue that time is stranger than everyday intuition suggests.
